I just watched a video they have on this API linked at the bottom of this page https://developer.paypal.com/docs/classic/products/paypal-payments-advanced/
It says that the "Enable Secure Token" should be set to Yes. I don't know if this has anything to do with the information we are trying to pass to PayPal but I have this set to No in Manager.
I believe that I read somewhere here in the forums just to leave it set to No and that's how I have others setup. As a matter of fact, I have most of the settings in Manager set to their defaults. I'm using template C but other than that, I change very little.
What should the AVS, CSC and Enable Secure Token be set to?
